When it comes to measuring the strength of a bag, of course there are the usual metrics like:
- Tensile properties of the paper used in manufacturing,
- Lab tests of the finished bag products measuring failure points (in kgf) for handles and bottom of the bag.
We knew we'd score at the top of these kinds of tests (and we did!), but these may be somewhat overrated when it comes to real-life use cases. Thus, we also wanted to test the bags as closely resembling real-life use cases as possible. With this in mind, we conducted countless tests, carrying all sorts of items in the bags, which we later categorized into 2 general buckets in the interest of ease-to-communicate. These were:
1- Static tests: The bag is held stationary, while loaded with an increasing number of items or with an increasing load on the bottom until either the bag or the handles rip apart.
2- Dynamic tests: FUN!!! We load the bags with what would be considered a typical heavy load (~2 gallons of water or milk in the USA, or about 9 liters of water in Europe - which is typically a 6 pack of 1.5 liter bottles). Then, we let them drop from pre-defined heights (waist high, shoulder high, eye level high, etc. ) and finish off with the most entertaining scenes:
Jumping up and down!!! :)
Here are 2 of our fun 40-second bag strength testing videos:
1- With 6 packs of 1.5lt standard water bottles, in a dynamic test
2- With BOWLING balls.
And, yes, we did load them with 6 gallons of water in a specially converted tomate cage, and we're surely always eager to show off our bag in the summer season with the heaviest of the watermelons in sight.
